I just bought a pair of D1 first & second stages. After the second dive (first dive in pool, second dive in the ocean) the circular black/white indicator face on the inhalation effort knob came off on one of my second stages. It appears to be a plastic piece with a foil back, basically a sticker. It's mostly a cosmetic piece and doesn't affect the regulator performance, but I'd still rather not have parts falling off my regs...
